In a statement carried by the Palestinian news agency Maan, the Gaza-based terror group said that the fire was its response to the death of Palestinian security prisoner Arafat Jaradat
in Megiddo Prison on Saturday.

"Liberty will be achieved through sacrifice. We must fight the enemy with all means necessary. The resistance will continue," the statement said.

The Color Red alert failed to sound prior to the incident. A military source told Ynet that the system recognized the launch as aimed at an open area, which does not trigger the sirens.

The Iron Dome
battery that was stationed in the area during the operation has since been redeployed.

The IDF said that "Iron Dome batteries are deployed and redeployed according to situation assessments and operational needs."

The defense establishment is scheduled to hold a situation assessment later on Tuesday

Defense Ministry official Amos Gilad told Ynet that, "Overall, our deterrence in the south is in place and peace in the area has been maintained, thanks to the IDF's successful operation.

"We do, however, have to remain vigilant to ensure no threat arises. This was a single event, but we have to make sure that peace and quiet are maintained."

Security forces have expressed concern that the growing unrest in the West Bank may
prompt the Gaza terror groups
to resume their rocket fire on Israel's south.

November's military campaign ended with an Egyptian-brokered armistice and various understandings between Israel and Hamas,
meant to maintain agreement.

The past few weeks have seen acceleration in the indirect talks between Hamas, Egypt
and Israel, in an attempt to galvanize the ceasefire agreement.

Several Israeli defense delegations have traveled to Cairo to that effect, while the Egyptians have stepped up their effort to curtail weapons smuggling into Gaza Strip.
